In a Facebook post, the U.S. Forest Service wrote that officials were patrolling near the Lower Sycamore Creek Recreation Area on April 3 when they discovered thousands of people who were gathering illegally.
Officials say campers and partiers restricted access by taping off sections of the main road to designate their camping area and vehicles were parked all along the main roads.
"Two quads colliding -- one person was medevac'd out by helicopter due to the restrictions caused by the partiers," forest service officials said.
Investigators say violations for visitors included DUIs, double riding, speeding/reckless vehicle operation, user-created vehicle staging areas in the burned area, camps blocking roadways, illegal use of fireworks, and target shooting with unknown backstops.
KPHO reported that by the end of the night, there had been seven crashes and multiple reports of stolen off-highway vehicles.
The Tonto National Forest did not immediately respond to Insider's request for additional comment.
According to the agency, a permit is required for non-commercial groups of 75 or more to use or occupy forest service land.
